Heating Coils
Product Introduction: High-Quality Mold Heating Coils
In the thermal control systems of plastic injection molds and hot runner systems, Heating Coils (also known as Heater Bands or Cartridge Heaters) are essential components for maintaining precise mold temperature and ensuring proper melt flow. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for heating efficiency, temperature uniformity, and durability of heating elements. Every heating coil undergoes rigorous testing to ensure consistent performance during long-term, high-temperature operation.
Self-Produced and Self-Used, Rigorously Selected
We are not only a supplier of mold components but also a mold producer ourselves. Through extensive practical experience in our own molds, we have repeatedly validated the heating efficiency, insulation performance, and temperature accuracy of heating coils. Only those with stable performance and exceptional durability are approved for our supply system.
Premium Materials, Precision Construction
Our heating coils are manufactured with high-quality materials including nickel-chromium (NiCr) resistance wire and high-purity magnesium oxide (MgO) insulation powder. The outer sheath is made from stainless steel or INCOLOY for excellent corrosion resistance and heat transfer. Precision winding ensures uniform heat distribution across the entire coil surface.
Multiple Types for Various Applications
We offer a complete range of heating coil types to meet different mold requirements:
Standard Heater Bands: Mica-insulated ceramic heater bands for general-purpose mold heating
Nozzle Heaters: Specialized coil heaters for hot runner nozzles and sprue bushings
Cartridge Heaters: Cylindrical heaters for insertion into drilled holes in mold plates
High-Temperature Ceramic Heaters: For applications requiring extreme temperatures up to 800°C
Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common diameters, wattages, voltages, and lead wire configurations to support quick dispatch. For non-standard customization, based on your mold requirements, we offer custom heating coils with:
Custom dimensions and wattage densities
Various lead wire types and lengths
Built-in thermocouple options for precise temperature control
Special voltages and configurations
We Can Also Source for You
